JOHN HENRY REEDER, OF GADDO, OKLAHOMA.

VISE.

To all whom it may concern:

Be it known that 1, JOHN HENRY REEDER, a citizen of the United States, residing at Caddo, in the county of Bryan and State of Oklahoma, have invented certain new and useful Improvements in Vises; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Vises, and more particularly to those which have a sliding jaw moved by a cam; and the object of the same is to produce a vise of this type for use by the blacksmith, wood-worker, or perhaps saddler, and so constructed that its reach may be contracted or expanded to fit v the work to be grasped by it and its movable jaw may be thrown into active engagement with said work by depression of a stirrup. This and other objects are accomplished by the construction hereinafter more fully described and claimed, and as shown in the drawings wherein Figure 1 is a side elevation of the vise. Fig. 2 is a front elevation of the same. Fig. 3 is a longitudinal section of the vise proper showing the beam in side elevation. Fig. 4 is a horizontal section taken on the line 4-4 of Fig. 3. Fig. 5 is a transverse section taken on the line 55 of Fig. 1. Fig. 6 is a detail perspective view of the loop and its dog. Fig. 7 is a detail vertical section through the rod and dog showing clearly the manner in which the rod is locked.

What may be called the fixed jaw in this vise is mounted upon a turret which comprises a base 5 having ears 6 screwed upon the workbench in the usual manner, a standaid 7 having an enlarged and preferably round lower end or turn table 8 centrally pivoted upon the base by means of a pin 9 as seen in Fig. 3, and the upper end of the standard is formed into the jaw 10 proper. Just below the latter through the standard is formed a rectangular opening of a size at its upper part to admit the free passage of the beam 11 which has a toothed rack 12 along its lower edge. Engaging the teeth of this rack is a spring-actuated pawl 13 pivoted in the reduced lower part of the opening below the beam, and the rear end of this pawl is adapted to be raised by depressing the outer end of a pivoted trigger 14 in am anner best seen in dotted lines in Fig. 5. This trigger is pivoted to the face of Specification of Letters Patent.

the fixed jaw and swings in a plane at right angles to the length of the rack, whereas the pawl 13 is pivoted within the opening in the standard or fixed jaw and swings in a longitudinal plane extendlng through said rack bar. It follows that when the trigger end of the standard, and the beam is adjustable through the latter at will.

Pivoted to the outer end of the beam at 15 is a cam 16 whose body is forked for that purpose, and the active face of the cam lies against the back of the movable jaw 17 which latter is thereby pressed toward the fixed jaw 10 when the cam is depressed.

These members are connected by a coiled spring 19 as best seen 111 Fig. 3, so that as the cam rises 1t retracts the movable aw and moves it away from the fixed jaw. The

outer end of the cam carries an arm 18, and

it is obvious that when this arm is depressed the cam will be turned upon its pivot 15 and the movable jaw will be pressed toward the fixed jaw so as to clamp the work between them.

\Vhen this improved device is intended to be operated by the foot of the workman I employ a rod 20 loosely attached to the outer end of the arm 18 and having at its lower end some foot mechanism such as a stirrup 21 into which the foot of the workman may be inserted. This rod passes loosely through the loop 22 best seen in Fig. 3, and the loop may be attached to the floor by means of a bracket or suitable means 23. Through one side of the loop passes loosely a dog 24 having an eye 25 at its inner end which loosely embraces the rod 20 when the dog stands horizontal, but is so disposed that when this dog is tilted upward slightly as shown in dotted lines in Figs. 1 and 2, the eye is canted to such an extent that it bites the rod and prevents further movement of the latter through the loop. However, when the outer tion of the eye on the rod ceases and the latter is again permitted to rise. It results from this construction thatwhen the workman places his foot within the stirrup and presses downward thereon, the rod is drawn downward through the loop and through the eye in the dog, but as soon as he releases pressure and the tendency of the rod is to rise, in doing so it cants the dog in place and causes its eye to bite the rod so that the latter can rise no farther. When it is desired that the rod shall rise, the dog is tripped by any suitable means as by the operators hand or foot.

Thus it will be seen that I have produced a vise whose standard is mounted on a turret on the work bench so that it may be revolved thereover to bring the outer end of the beam to a point beyond the edge of the bench when the foot mechanism is to be attached although when the latter is detached the vise may be swung around to any position desired by the workman. Having inserted his work between the jaws and across the beam, he pushes the latter and the movable jaw with it toward the fixed jaw so that the beam and ratchet teeth slide through the opening and over the pawl in a manner which will be clear, then by depressing the arm 18 (either manually or through the foot mechanism) the cam is caused to move the movable jaw toward the fixed jaw to clamp the work firmly and hold it there until pressure is removed.

All parts of this device are of the desired sizes, shapes, proportions and materials, ex-

cepting that of course I prefer metal for the latter; and considerable change may be made in the details of construction without departing from the essential principle of my invention.

What is claimed as new is:

1. In a vise, the combination with an upright standard pivoted upon a base and having through it an opening which is rectangular at the upper portion and reduced in width at the lower portion, the upper end of said standard forming the fixed jaw, a beam slidable through the larger part of said opening and having teeth on its under side, a movable jaw mounted slidably upon said beam, and means for setting it thereon; of a spring-actuated pawl pivoted in the smaller portion of said opening with its tip normally engaging said teeth and its other end projecting out of such opening, and a rectangular trigger pivoted to the face of the standard at one side of the lower end of said opening and moving in a plane at right angles to that in which said pawl moves, as and for the purpose set forth.

2. In a vise, the combination with an upright standard carrying a fixed jaw and having an opening through it, a beam passing through said opening, means for adjusting its position therein, a movable jaw slidably mounted on said beam, and a cam pivoted to the outer end of the beam behind the movable jaw and having an arm; of a rod hanging from the outer end of the arm and having foot-mechanism at its lower end, a fixed loop through which the rod slides loosely, and a dog pivoted through one side of the loop and having an eye loosely engaging said rod and adapted when canted to bite the rod and prevent upward movement thereof.

3. In a vise, the combination with an up right standard carrying a fixed jaw and having an opening through it, a beam passing through said opening, means for adjusting its position therein, a movable jaw slidably mounted on said beam, and a cam pivoted to the outer end of the beam behind the movable jaw and having an arm; of a rod hanging from the outer end of said arm and having foot mechanism at its lower end; a loop through which said rod moves freely, a bracket connecting the loop with the fioor, and a dog pivoted through one side of the loop and having an eye loosely engaging said rod and adapted when canted to bite the rod and prevent upward move ment thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
